Producer Chris Sigaty responded to those concerns during a recent interview with Shacknews, telling us that the team is viewing the games as traditional Blizzard expansions, and not full sequels. nope "We effectively look at it internally as expansions," said Sigaty. "So we'll see what that means for the price--we're not just going to raise it and call it that for the purposes of that. We would need to offer the same content."
Sigaty's guess is that the two expansions--the Zerg-centric Heart of the Swarm and the Protoss chapter Legacy of the Void--will not offer the same content as the original, and thus should be priced accordingly.
"I think internally, we want to do it a little bit fast, get a full campaign out there with enhancements to the multiplayer game," he said. "And in doing so, it would likely be an expansion-level product, and a Blizzard expansion-level product, but still something that doesn't quite have the same content as the original."
Of course, as the recent delay proved, nothing is set in stone at this point.
"We're going to value it at what it's worth," he added. "And honestly, internally, how we look at it, we look at it like it's the Frozen Throne and the Frozen Throne 2, or Brood War and Brood War 2. We think we're adding at least that amount of content, but we're not going to gouge people. We're going to charge them what's fair."
